Method Approach

This paper investigates the guaranteed cost control of chaos problem in permanent magnet synchronous motor (PMSM) via Takagi-Sugeno (T-S) fuzzy method approach. Based on Lyapunov stability theory and linear matrix inequality (LMI) technique, a state feedback controller is proposed to stabilize the PMSM systems. An illustrative example is provided to verify the validity of the results developed in this paper.

New System

This paper presents a novel means of designing a nonlinear controller for Permanent Magnet Synchronous Motor (PMSM) based on the method of control Lyapunov function.The most important of it is to find out an appropriate Lyapunov function to design control law by coordinate conversion so that the new system can be globally asymptotically stable.Simulation results clearly show that the proposed controller has good dynamics performance despite disturbances are loaded.
